Polybenzimidazoles were studied as potential ferroelectric polymers after a model, 2-ethylbenzimidazole, was shown to be ferroelectric. Three polymers were studied as the formate salts. They were interesting and showed large polarization, but were not pyroelectric or ferroelectric. One polymer may be antiferroelectric with T(c) = 40 C. Nylon 11 was shown to be polable and was then pyroelectric. (Author)
